(3) energy source: energy that may endanger people, including compressed air, nitrogen, gas, gravity, elastic force, pressurized water, hydraulic pressure and steam.

(4) energy isolation devices: devices that physically prevent the release or transmission of power, including but not limited to: manually operated electrical circuit breakers; Manually operated safety switch; Valves in pipelines (locks on pipeline valves are not a substitute for blind plate work), plugs, and other similar devices that block or isolate power sources. (buttons, selector switches and other similar controls cannot be used as power isolators)

(v) authorized staff: refers to the staff who performs locking and listing for the service or maintenance operation of the machine and equipment. They must be qualified and authorized staff who have been trained and examined for locking and listing.
